Hi,

I am facing little probl= em with Xenomai tasks. Please help me.

I am using Xe= nomai 2.5.6 patched to Kernel 2.6.37 on Intel Atom board with display and t= ouch
interface. I have created an application which uses various Linux D= rivers such as
Serial Driver - Configured and used using tty layer.
D= isplay driver - Intel Frame buffer interface (mmap and ioctl).
Socket Pr= ogramming and file system handling.
When I run this application without having any Xenomai tasks then application works fine,
but when I create= different tasks then application does not work correctly. Especially Seria= l
interface and display. Serial data seems to be loosing data and displ= ay update is not happening instantly.
I am sure I am missing something. = Please help me to=0A resolve this issue.
I am using following functions = to create and maintain Xenomai tasks and tasks are successfully created.
   &= nbsp; mlockall(MCL_CURRENT | MCL_FUTURE);
&nbs= p;    rt_task_set_mode(0, T_WARNSW , NULL);
=      rt_task_create();
&nb= sp;    rt_task_start()
   &nb= sp; rt_task_yield() - To allow execution of other tasks.

Thanks & Best Regards,
Sanjay
